PUBLISHED JANUARY 6, 1970 T870,002 PRODUCTION OF PERMANENTLY PRESSED 0RCREASED FABRICS John H. Davis, 2375 Mountain Drive 37664, and Charles H.Coney, 2008 Canterbury Road 37660, both of Kingsport, Tenn.

Filed Sept. 11, 1968, Ser. No. 759,239 Int. Cl. B06111 1/24 US. Cl.117-11 No Drawing. 9 Pages Specification A method of treating a fabriccontaining cellulosic or natural fibers is disclosed. The methodcomprises applying to the fabric to be treated a tertiary amine oxidewhich is a solvent for the fabric, and subsequently applying heat andpressure to the tertiary amine oxide-containing fabric to partiallysolvate or temporarily soften the fabric and provide a permanent pressor crease thereto. The treated fabric may then be rinsed to remove thetertiary amine oxide. The heat press may be applied either to a fold inthe fabric to form a permanent crease, or to a flattened area to form awrinkle-resistant fabric. Fabrics treated in this manner are not subjectto degradation by chlorine since the oxide may be worked out. Examplesof tertiary amine oxides which may be used includeN-methylmorpholine-N-oxide, trimethyl amine oxide, triethyl amine oxide,tripropyl amine oxide, and the like.
